It’s weird actually because going down on him doesn’t give me any physical pleasure other than getting super wet… whereas I can orgasm multiple times through penetration.
He just has the most delicious cock that fits in my mouth perfectly. Not too lengthy so that I can force it down my throat without dying—I may choke on it a little, but that’s the whole point :) Yet incredibly girthy so that my mouth is usually stretched open wide and I have to drool all over it for it to slide in and out of my lips easily.
I think about it when I’m masturbating, when I’m dreaming even, in excruciating detail. Every vein on his shaft, every groove of the head of his penis. I fantasize about how I’d suck it; at first just the tip, then wrap my lips down his shaft inch by inch. Then I’d tongue the very tip, where he’s already dripping precum, and of course the underside of the head, which is responsible for so many of my own orgasms!
